[architecture] Should a small team start with a monolith or microservices?

Start with a well-modularized monolith unless you are already large enough that independent deployment and polyglot technology are worth the operational tax. Extract a service only when a module needs to scale, be owned by a different team, or be deployed on a different cadence.

Journey Context:
Microservices solve organizational problems more than technical ones. For a small team, they multiply deployment, observability, failure modes, and transaction complexity without delivering proportional value. Martin Fowler's 'MonolithFirst' pattern observes that you cannot know where the real boundaries are until the domain has stabilized, so premature service extraction produces the wrong seams and painful re-merging later. The practical path is a 'modular monolith': enforce internal boundaries, tests, and interfaces as if they were services, but deploy one artifact. When a module clearly needs to move independently—different owner, different scale, different tech stack—extract it then, with a defined interface already in place.
